Yellowstone grizzly bear kills tourist

A female grizzly bear killed a man who was hiking with his wife in Yellowstone National Park after the couple apparently surprised the animal and its cubs.

It was the park's first fatal grizzly mauling since 1986, but the third in the Yellowstone region in just over a year amid ever-growing numbers of grizzlies and tourists roaming the same wild landscape of scalding-hot geysers and sweeping mountain vistas.
